vine trellis for neighbors

This is a redwood trellis for our neighbors to support their passion flower vine which has recently collapsed. The size: 6’6” tall, 40” wide. It’s finished with one coat of redwood color penetrating oil; I considered marine spar varnish for finish, but the redwood is very soft. I thought the varnish film would get scratched and dented easily.

In this design no screws or nails are used, except for attaching the bottom rail to the end grain of the legs. The entire structure is held together by half lap or dado joints fortified by polyurethane glue.
